I used photopass for the first time in December and really enjoyed it, I preordered so the price was a value, by the time I ended up editing the photos I think I had 250 photos on it.
I was disappointed with the photopass in one aspect, there were not photographers at the character meals which is the one reason that I had decided to do it. At Chef Mickeys (and probably others that I didn't dine at) we could have had our pictures "added to" our photopass that were done when entering the restaurant......once I had bought their pictures! That didn't interest me at all, over priced/oversized pictures, I only plan on printing out my photopass pics in 4x6 size to use for scrapbooking.
But there are plenty of photopass sites throughout the parks, we did many of them at all the parks, less at Epcot for some reason, they didn't seem as plentiful. It was nice to have all 3 of us in the pictures instead of someone missing as they manned the camera.
I doesn't cost you a thing to get a card (or 2 or 3) and take pictures, some of them are priceless. The cards can all be combined on one photopass. Buying it as a preorder worked out easily, and it has a guarantee that says if you can get a full refund.........so if I didn't like any of the pics or didn't take enough to warrent the expense then I could have gotten a refund.
